Fresh from her headline-grabbing double date with Katy Perry and John Mayer at the Grammys, actress Allison Williams, one of the break-out stars on HBO’s hit show Girls and daughter of NBC Nightly News anchor Brian Williams, is sharing her anti-break out skincare secrets as the new face of Simple®, a range of facial skincare products that won’t irritate sensitive skin.

As part of the new campaign, the 24-year-old, who plays gorgeous but down-on-her-luck Marnie Michaels on Girls says she relies on Simple® products to counter the many factors that irritate her sensitive skin. These include makeup, weather, and pollution. Simple® products don’t contain dyes, artificial perfumes, or harsh irritants that can upset skin. Williams’ new Simple® television commercial debuted nationwide on February 11, 2013

“As a longtime fan of Simple skincare, I was so excited when they approached me about becoming their brand ambassador,” says Williams, in a news release. “I love that their products keep my skin healthy-looking, without irritating it, because Simple is made for sensitive skin, like mine.”

Williams made her first public appearance as the new face of Simple® on February 6, 2013, at a New York City red carpet premiere for the documentary MAKERS: Women Who Make America, proudly presented by Simple®, which will air on Tuesday, February 26 at 8 p.m. ET on PBS (check your local listings).
